After experimenting a bit, Fullscreen 2 seems to cap the game's framerate at 60fps. I don't know if this was intentional (possibly as a performance-limiting feature for lower-end PCs or less heavy-duty graphics cards) or not, but just as a heads-up since Dragami has advertised the PC version as having uncapped framerates that you will need to switch to Windowed or Fullscreen 1 (borderless) mode if you want more than 60fps.
